Electric Fields

[Neuronic]

I'm trying to understand the concept of the Electric Field. Is it a force itself? Or its some abstract piece of energy that generates a force?

I don't really get how its different from a force. Isn't it referred to as a "force field"?

As far as I know, it's not exactly a force.
An E-field is defined as followed:
\vec E \equiv \mathop {\lim }\limits_{q_0 \to 0} \frac{{\vec F}}{{q_0 }}

Here is q_0 a test charge and \vec F the electric force.
Therefore, an E-field is a force per charge so in N/C.

Since I didn't really know how to explain you this further, here's a quote from the Wikipedia: "an electric field or E-field is an effect produced by an electric charge that exerts a force on charged objects in its vicinity.".

Hope that helps :smile:
